Detective Comics #938 delves into a bit of the backstory behind the Colony and Kane’s obsession with a secret arm of the League of Assassins which Batman doesn’t even believe exists.

Detective Comics has quickly become my favorite team book of the relaunched Rebirth comics. The issue works in Batman without him taking to spotlight from the rest of the team. Now that the Bat Family is back together the question becomes what’s their next move against the Colony? And just how far will Jake Kane go to save what he’s built? Worth a look.
